strong and substantial metal journal ends and novel means for securing these ends on the body because I know that in practice it not infrequently happens that the journal ends are broken or distorted in use or in handling andwork or are forced suificiently free to revolve on the body or to permit the body to revolve relative thereto. The journal ends of my invention are strong and substantial and are rigidly and permanently secured to the body.

I have shown the invention in a preferred form adapted for cemmercial use, but I reserve the right to make changes in the construction and arrangement of parts within the scope of the following claims.

I claim: 7

. 1. A spindle for gelatin band rolls having a body, and end members rigidly mounted on the ends'of the body and each having a centrally disposed journal and a plurality of outwardly projecting peripheral lugs spaced apart and spaced from said centrally disposed journal. r

2. A spindle for gelatin band rolls having a body, and end members rigidly mounted on the ends of the body and each having a pluralit-y of outwardly projecting spaced peripheral lugs and a centrally disposed ournal projecting from the end member beyond the lugs and radially spaced from said lugs.

3. A spindle for gelatin band rolls having a body, and end members rigidly mounted on the ends of the body and each having plurality of spaced lugs projecting in the direction of the length of the spindle at the periphery thereof, the opposing sides of the lugs being disposed radially of the spindle.

4. A spindle for gelatin band rolls having a body, and an end member having a socket into which an end of the body is inserted, the bottom of said socket and the end of said body having a rib and groove engagement to prevent relative rotative movement of the end member and body.

5. A spindle for gelatin band rolls having a body, and an end member mounted on an end of the body, said member having a socket into which an end of the body is inserted, and the inner wall of the socket being provided interiorly with a longitudinal sharpened rib ,to take into the body when the body is forced into the socket and to prevent relative rotative movement of the end member and body.

6. A spindle for gelatin band rolls having a body, and an end member mounted on an end of the body, said member having a socket into which an end of the body is inserted, the bottom of said socket and the end of said body having a'rib and groove engagement, said socket being provided on its inner wall with a longitudinal sharpened rib to take into the body when the body is forced into the socket to prevent relative roative movement of the end member and body.

7. A spindle for gelatin band rolls having a body, and an end cap member mounted on an end of the body, said end cap member forming a socket into which an end of the body is inserted, the inner wall of said socket being provided with a longitudinally disposed sharpened rib embedded into the body and said wall being indented into the body to secure the end member rigidly on the body against relative rotative and longitudinal movement thereon.

8. A spindle for gelatin band rolls having a body, and an end member mounted on an end of the body, said end member having a socket to receive an end of the body, the bottom of said socket and the end of said body having a rib and groove engagement, and the wall of said socket being provided interiorly with a sharpened rib to take into the body when the body is forced into the socket and said wall being indented into the body to secure the end member rigidly on the body against relative movement thereon.

9. The combination of a journal support having a lug thereon, a gelatin band roll spindle, a journal at an end of the spindle to engage said support, and a plurality of outwardly projecting spaced peripheral lugs arranged about and spaced from the journal on the end of the spindle and adapted for engagement with said lug on the support.

10. The combination of a gelatin band roll spindle having a plurality of outwardly projecting spaced peripheral lugs and a centrally disposed journal at an end of the spindle, and an adapter having a threaded stud to engage a support, a lug to engage a space between two of the lugs on the spindle, and

an opening to receive the journal.
